Why should Prevacid not be prescribed?
Do not take Prevacid if you’ve ever had an allergic reaction to it, or if you’ve ever had an allergic reaction to penicillin or macrolide antibiotics, such as clarithromycin or erythromycin. You must also avoid Prevacid if you’re taking cisapride, pimozide, astemizole, or terfenadine. Combining Prevacid with these drugs could cause dangerous—and even fatal—heartbeat irregularities.
